How to Display MySQL BLOB Images in an HTML `` Tag?

Retrieving and Displaying Images from MySQL in an HTML Tag

Question:

You have created a MySQL database and a table with a BLOB column to store JPEG files. While attempting to retrieve the image data into an HTML tag, you're encountering issues with the PHP variable $result. How can you incorporate $result into the HTML to display the image?

Answer:

It is not possible to directly include the $result variable in the HTML tag. The $result variable contains the raw image data retrieved from the database. To display the image, you need to create a separate PHP script that will output the image data.

Solution:

1. Modify catalog.php:

   • Change the HTML tag to refer to a new PHP script that will retrieve and output the image data:

     <img src="getImage.php?id=1" width="175" height="200" />

     Copy after login

2. Create getImage.php:

   • Create a new PHP script named getImage.php that performs the following tasks:

     <?php
     
     // Establish database connection
     $link = mysqli_connect("localhost", "root", "", "dvddb");
     
     // Prepare SQL statement
     $sql = "SELECT dvdimage FROM dvd WHERE>

     Copy after login

This script establishes a database connection, executes the SQL statement to retrieve the image data for the specified ID, sets the image content type header, and outputs the image data.

Explanation:

By creating a separate script to retrieve and output the image data, you can separate the database operations from the HTML display. This approach ensures that your HTML code remains clean and organized.
